Patent CA-2187102-A1 (CA)
Inventor: HOEBEKE RUDY GEORGES
IPC: H04L12/56
Filed: 1996-10-03
Abstract: A bursty traffic multiplexing arrangement (A) includes a multiplexing unit (MUX) to multiplex a plurality of bursty input flows (IF1, ..., IFI, ..., IFN) into an output flow (OF). Congestion due to insufficient throughput capacity of the multiplexing unit (MUX) is avoided by incorporating an input shaping device (ISDI) for each input (MII) of the multiplexing unit (MUX). Data elements constituting such an input flow (IFI) are stored in an input buffer (IBI) which forms part of the corresponding input shaping device (ISDI), and are applied to the multiplexing unit (MUX) at a rate (BI) which does not exceed a predetermined maximum input buffer reading rate (BIMAX) associated to this input buffer (IBI). Furthermore, via feedback input flow rate control information (IFRI), the input flow rates (A1, ..., AI, ..., AN) can be controlled to thereby avoid inputbuffer overload.

Abstract: The disclosure relates to a laser (L) and to at least one detector integrated side by side on one and the same substrate so that the laser emits, through the edge of the device, a light beam along a direction and so that the detector can detect, through the same edge of the device, a beam substantially parallel to this direction of emission.  In a system for the optical reading of a recording medium, the light emitted is reflected by the medium to be read to the detector or detectors.  A diffraction grating (RZ) that diffracts only diffraction waves with the same sign (positive for example) deflects at least a part of the light to the detector or detectors.  Application to the reading of optical disks.

Patent CA-2193906-A1 (CA)
Title: Heating and humidifying respiratory mask
Inventor: BEHR R DOUGLAS
IPC: A62B18/00
Filed: 1996-12-24
Abstract: A light-weight face mask can heat and humidify inhaled air with previously-exhaled air by passing the air through a highly-effective and highly-efficient heat exchanger dis-posed within the mask. The heat exchanger has a multitude of layers of metallic mesh through which the air passes generally lincarly. The warm exhaled air heats the mesh which in turn heats the incoming air before it is inhaled. Moisture from the exhaled air condenses on the relatively-cool heat exchanger and humidifies the incoming air. Inhaled air enters the mask generally upwardly, and exhaled air exits it generally downwardly.

Patent CA-2195725-A1 (CA)
Inventor: KLEINHEN STEPHEN R
IPC: B65H45/16
Filed: 1997-01-22
Abstract: A sheet material handling apparatus includes a collator conveyor, a hopper, and a sheet material handling assembly.  The sheet material handling assembly removes sheet material articles from the hopper, folds the sheet material articles, creases the sheet material articles, and deposits the sheet material articles on the conveyor.  The sheet material handling assembly includes a rotatable drum having grippers which grip a sheet material article.  A folder assembly forms a fold in a central portion of the sheet material article while the sheet material article is held by the grippers and the drum is rotated.  A creaser assembly creases the fold during continued rotation of the drum.  The gripper assembly is then operated to release the sheet material article for movement toward the conveyor. Thereafter, the creaser assembly releases the sheet material article and the sheet material article is deposited on the conveyor.
Patent CA-2196860-A1 (CA)
Title: Knife gate valve with mechanically retained gate seat
Inventor: YOUNG CALVIN L
IPC: F16K3/02
Filed: 1997-02-05
Abstract: A knife gate valve comprises a body member to which two aligned conduits are attached. The body member has a U-shaped internal recess of predetermined length formed within it. A removable sealing member fits within the recess and extends along its entire length. The sealing member is comprised of rubber which has been cured about a threaded or irregularly surfaced rod that reinforces the seat, helping to keep it in the correct position and orientation in the recess. The rod protrudes from both lengthwise ends of the rubber and is operatively connected with the body of the valve. This prevents the sealing member from being dislodged by the flow of slurry through the valve or the opening action of the valve in the presence of a sticky slurry.

Title: Adjustable wheelbase wheelchair
Inventor: ROGERS RICHARD H
IPC: A61G5/10
Filed: 1996-05-14
Abstract: Applicant's invention is of an improved multi-wheeled vehicle having adjustable wheelbase dimensions. The preferred embodiment is a wheelchair (10) which is adjustable as to length and width "on-the-fly." Contracting the two side frames (22) effects a simultaneous retraction of the forward wheel struts (30). Thus, the length of the wheelchair (10) is reduced at the same time the width is reduced, and vice versa. The linkage between the two side frames (22) is preferably two cross members (46) in an X configuration, one end of each cross member (46) being pivotally affixed to one side frame (22) on one side of the wheelchair (10), with the respective other end of each cross member (46) being pivotally affixed to a wheel strut (30) on the opposite side of the chair (10), the two wheel struts (30) each being slidably attached to a respective side frame (22).

Patent CA-2201292-A1 (CA)
Title: Temperature compensated logarithmic converter
Inventor: NORDHOLT ERNST
IPC: H03G7/00
Filed: 1995-09-26
Abstract: A logarithmic convertor based on a nonlinear successive detection principle has a temperature-compensated biassing arrangement and a large operating range due to a d.c. feedback network for offset reduction and an attenuating input stage permitting large input voltages. The log converter exploits the exponential relationship between the collector current and base-emitter voltage of a bipolar transistor to render the converter insensitive to temperature and process parameter variations. The converter is a cascade of sections, each having a constant-gain differential amplifier having a particularized current source. The constant-gain amplifier may include a Darlington differential pair, and the current sources have outputs that are either temperature-independent or proportional to temperature.

Patent CA-2208624-A1 (CA)
Inventor: FRAZER HUGH
IPC: A61C7/08
Filed: 1997-07-08
Abstract: A custom, intra-oral apparatus in two parts which prevents intense contraction of the elevator muscles of the mandible by triggering the Jaw Opening Reflex. The upper part of the apparatus fits over the maxillary six anterior teeth forming a smooth, flat platform, anteriorly following the curvature of the teeth with a flat posterior border, running from the cuspid to the cuspid across the palate. The lower part of the apparatus fits over the four mandibular incisors and has a small dome located over the longitudinal axis of the two central incisors at the midline.When the upper and lower teeth are brought together, the dome of the lower part of the apparatus engages the flat platform of the upper, thus directing the force exerted by the muscles down the long axis of the lower incisors. This action triggers the Jaw Opening Reflex and causes the muscles to relax ( to prevent damage to these teeth ). Intense contraction of the elevator muscles of the mandible during the R.E.M. phase of sleep has been implicated in the complex etiology of chronicheadache, tension- type headache and migraine headache pain. This apparatus is designed to be worn while asleep and, by preventing the intense contraction of the elevator muscles of the mandible, considerably reduces the incidence of headaches.This two part apparatus overcomes the shortcomings of previous known art consisting of only one part, because of its definitive prevention of contact of the posterior teeth.
